CFP SR10 100GbE 100m CFP Transceiver
Features Integrated 10 independent full duplex channels Transmission distance up to 100m (MM fiber) Support CFP MSA and CAUI electrical interface Compliant to IEEE 802.3ba 100Gbase-SR10 Control functions through the CFP management interface CFP Power Class 1 (<8W) RoHS 6/6 compliant
Description The transceiver is a hot pluggable fiber optic transceiver in the CFP form factor. Integrating 10 independent channels of 10G transmitting and receiving functions makes it ideally suited for 100G very short reach applications where cost effective high bandwidth is needed. The diagnostic and control functions are integrated into the design via a set of non-data hardware signal pins and Management Date Input/Output (MDIO) interface per the CFP Multi-Source Agreement (MSA) Management Interface Specification draft 1.4. The transceiver supports an aggregate bandwidth of 100G over 100 meters of optical fiber. Each lane transmits and receives data streams at typical data rate of 10.3125Gbps. The CFP transceiver has a single MPO port which connects to an industry standard 2x12 multi-mode fiber cable. It provides an excellent solution for 100GbE data transmission at 850nm over up to 100m multimode mode ribbon cables. The product is designed and tested in accordance with industry safety standards. The transceiver
is Class 1 Laser product per U.S. FDA/CDRH and international IEC-60825 standards. The transceiver connects to standard 148-pin CFP connectors for hot plug capability. This allows the system designer to make configuration changes or maintenance by simply plugging in different transceivers without removing the power supply from the host system. The transmitter and receiver DATA interfaces are internally AC-coupled. LVCMOS Transmitter Disable control input and Loss of Signal (LOS) output interfaces are also provided. The transceiver can be conveniently assembled into and released from the host system through the railing system specified in the CFP MSA. The transceiver operates from a single +3.3V power supply over an operating case temperature range of 0°C to +70°C. The housing is made of metal for EMI immunity.

Application Notes Electrical interface: All signal interfaces follow the CFP MSA specification. The high speed DATA interface is differential ACcoupled internally and can be directly connected to a 3.3V SERDES IC. Hardware control and status reporting pins are 3.3V LVCOMS compatible. The MDIO interface pins are 1.2V LVCOMS compatible and should be pulled up with a 4.7 - 10kΩ resistor on the host board.
TX Disable: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled. The laser is also disabled if this line is left floating, as it is pulled high inside the transceiver. Receiver Loss of Signal (RX_LOS): The Loss of Signal circuit monitors the level of the incoming optical signal and generates logic HIGH when an insufficient photocurrent is produced. The RX_LOS is the logic OR of the LOS signals from all the input receiving channels in the CFP module.
MDIO Interface: Upon module initialization, the alarm, control and monitor functions are available through the MDIO interface. The interface consists of 8 wires including 2 wires of
MDC and MDIO, as well as 5 port address wires, and the Global Alarm wire. MDC is the MDIO clock line driven by the host and MDIO is the bidirectional data line driven by both host and module depending upon the data directions. The MDIO port address pins PRTADR0:4 are used for the system to address all of the CFP ports contained within a host system PRTADR0 corresponds to the LSB in the port addressing scheme. The 5-wire port address lines are driven by host to set the module port address which should match the address specified in the MDIO frame. The Global Alarm pin (GLB_ALRMn) is an output pin to the host. It asserts low on any fault/alarm/warning/status conditions that has been chosen. It is driven by the logic OR of all unmasked fault/alarm/warning/status conditions latched in the latched registers. The data transfer protocol and the details of the mandatory and vendor specific data structures are defined in the CFP MSA Management Interface Specification draft 1.4. Power supply and grounding: The power supply line should be well-filtered. All power supply bypass capacitors should be as close to the transceiver module as possible.

Interfacing the Transceivers Communication is via a set of non-MDIO hardware control and signal Pins and the MDIO interface. The MDIO management frame, set of CFP resisters and the set of rules for host control, module initialization, and signal exchange between Host and the transceiver is described in the document CFP MSA Management Interface Specification draft 1.4. Addresses from 0000h to 7FFFh are reserved for IEEE802.3. The CFP register space starts from 8000h to FFFFh.
